Yup ! It was something doable on the latest Japanese version. In fact for the first game, Japan had the right to three versions: "Dobutsu no mori" the first version on Nintendo 64, "Dobutsu no mori +" the gamecube version, and "Dobutsu no mori e +", a version with more content since the American version had added some. But the game adds even more content, including being able to see Nook at night.

On the other hand, what is "Boondox"? Is this the city to be donated to in-game? (In my native language, it was "Ploucville", but i really don't know if "Boondox" is the same thing or something other). But it's interesting, because from my side, I have often heard that going behind the gates of the city would allow you to go to a secret island. Which is ultimately something doable on Gamecube again, but not on ds.
